From Data to Parts

From Data to Parts


 LaserStates will show the whole process from 3D data to the finished parts.

Background

This black plastic part is named "Roller" which is installed on the shaft in the copy machine driven unit to fix the shaft.

The diameter of the hole and the support dimension in the hole is very important for this part.
Some times, the support is defective due to adhering to mould. It effect the process very much.

LaserStates suggest the customer using SLA printer to process this part.

File

Customer sent the 3D data (STL file) to LaserStates CT Data from Hospital is acceptable.

 

Supports Adding

LaserStates add the supports on the parts in Simulation Software and define the printing datum

SLA Printing
 

The data was input to the SLA printer, after setting the parameter, the printer start printing
 

 

UV Curing Process

The printed parts were placed in the UV Curing Chamber, sart the UV Curing Process


 

Cleaning and Inspection

Remove the supports, then clean the parts, finish the Whole process. The white part is SLA printed part.

Please send the 3D files to sales@laserstates.com to get Quick Quotes.


Injection Process
 

Here, LaserStates would like to introduce the process of Injection Parts.
 

How to process a mould?
Mould Design according to the parts → Mould parts design → Mould part machining → Mould assembly
 

Next Step, the mound is installed in the Injection Machine.
→ Plastic Material Drying, Mould Heating
→ Injection Technique Setting
→ Trial Process
→ Start the mass production after the first article part is approved
 

Injection Process Difficulties

 

The designers should be familiar with the Injection Technique and the injection machine, otherwise, perhaps his design could not be processed by the injection machine.

 

For injection parts, Engineers should understand

1) Keep Wall Thickness Consistent
2) Provide for Proper Gate Location
3) Determine Optimal Wall Thickness
4) Radius Corners Generously
5) Select Suitable Draft Angles

 

 

 

 

The designers should be familiar with the Injection Technique and the injection machine, otherwise, perhaps his design could not be injected successfully or there are many defects on the parts.Following are main defects happened in the injection parts.

Photo Number Defect Description Main Reason
1 Sliver Marks The raw material hasn't been drying enough, etc.
2 Short Shot Temperature is too low or the area is far away from the gate, etc.
3 Burnt Streaks Temperature is too high, etc.
4 Visible Ejector Marks Injection pressure is too high, etc.
5 Dark Sport The raw material is dirty or the mould is dirty, runner is dirty, etc.

 

The 3D printer could printed all shapes, it will take less time in study the plastic technique for the designers.
